Speed

Speed is the technique in the Devil May Cry games which focuses on fast sprinting. It is mainly used for the burst of speed in the game, where normal running is slow while wandering in the environment. Once unlocked, the running speed will be increased after a few seconds of running. As the player would 'break' air while sprinting causing the feet to move faster than normal.

Other effects
Aside from increasing running speed, this skill also provides alternate uses;
 * As Nero in Devil May Cry 4, pressing the taunt button activates the Rainbow - A classic two-foot kick demonstrated after a fast run. This can knock enemies backward, and may cause high damage when targeted at an enemy's head.
 * While running to a ledge or cliff with Speed, you can perform a fast horizontal jump, able to cross large gaps, or descend quickly.
